I was just testing my DPS on a dummy a moment ago. I had been keeping constant DPS for a few minutes when something struck me as odd. I noticed my health was pretty low (due to me using Shadow Word: Death for mana returns). So I checked the healing meters and it turns out healing from Vampiric Embrace only procced 143 times, which almost matched my number of Mind Blast/SW: D/ Improved Devouring Plage casts.
Anyways I was wondering, has VE been nerfed so it doesn't proc from DOTs anymore or have I perhaps been living in a cave and not noticed it until now?
By the way, over a period of a little over 9 minutes the meters show that Vampiric Embrace only had a little over 4100 healing done total
